7. Troubleshooting
This section describes common causes, and solutions to, problems and alarms that you may encounter while using the Airvo 3. The
Airvo 3 Technical Manual contains additional information that may be helpful in resolving more advanced problems.
7.1 Alarms
The Airvo 3 has visual and auditory alarms to notify users about interruptions to a patient’s treatment. These alarms are generated by an
intelligent alarm system, which processes information from sensors and target settings of the device and compares this information with
pre-programmed limits. Changes to alarm settings will be preserved during or after any power loss.
The signal light fl ashes and troubleshooting information is displayed on the Airvo 3
touch screen when any alarm is active. The color of the signal light indicates the
highest-priority active alarm condition.
7.2 Alarm priority
Alarms are grouped by urgency and severity into three priority levels: low, medium, high. When multiple alarms are active, the audible
alert, signal light and Message bar background color will signal the highest-priority alarm active.
• A response is needed for all alarms.
• A prompt response is required for all medium-priority alarms.
• An immediate response is required for all high-priority alarms.
